Getting some Attribute Errors when making shifts if using a newer version of python.

    sentiment_shift = sh.WeightedAvgShift(type2freq_1=type2freq_1,

                          ^^^^^^^^^^^^^^^^^^^
AttributeError: module 'collections' has no attribute 'Mapping'

It's an easy fix, just need to change line 156 in helper.py from

    if isinstance(scores, collections.Mapping):

to

    if isinstance(scores, collections.abc.Mapping):

Actually, if you want to make it backward compatible and not deal with different versions of shifterator for different versions of python, I would add something like this:

try:
    from collections.abc import Mapping
except ImportError:
    from collections import Mapping

in the imports and then just edit to have Mapping on line 156

if isinstance(scores, Mapping):

instead of the existing collections.Mapping
